Preparation to anchor a buoy on the edge of a pool area, a worker uses a rope to lower a square block of concrete, 0.25 m on each edge, the ocean water. The block is moved downward at a constant speed of 1.9 m / s. You can assume that the fluid is incompressible block. (A) At what rate is the force exerted by the water on the underside of the block increase? (B) At what rate is the driving force on the block increase?
This is a bit strange -. for (b) I am sure thrust force does not change ….. Archimedes' principle applies and does not mention any dependency on the depth. The buoyant force depends on the pressure difference between the top and bottom of the object and an incompressible fluid that remains constant, no matter what depth. bu (s )???? Because the pressure is increasing with depth, the force at the bottom of the block will be increased (remember that is also growing on the upper side of the block and the two extensions to balance). Any rate increase will be registered as a certain number of newtons per second …. . Gain in-depth per second = 1.9 m. Increased pressure DP = gp DELTA.V where p = density of water Increased strength = DP. A = gp. 1.9. 0.25 p ^ 2 = 1.2 N / s, but only a silly thing to exercise.
